The new metric exposes whether the last scrape of RabbitMQ was
successful. It is inspired by the haproxy_exporter which exposes the
metric
haproxy_up
.The value of
rabbitmq_up
is either1
or0
. It can be used todetermine whether the RabbitMQ process being scraped is up-and-running.
In order to be able to set the metric, some functions have been
rewritten to return error values instead of using callbacks.
